According to another preferred embodiment
vorgesehen, dass der Rastzapfen und das Rastloch einen Kegelwinkel zwischen < α < 45°, vorzugsweise zwischen 1° < a < 20° aufweisen. Ein kleiner Kegelwinkel zwischen 1° < ^ 20° eignet sich bevorzugt für steife und provided that the locking pin and the locking hole have a cone angle between <α <45 °, preferably between 1 ° <a <20 °. A small cone angle between 1 ° <^ 20 ° is preferred for rigid and

Ein Kegelwinkel zwischen < α < 45° eignet sich somit in Abhängigkeit des gewählten Kegelwinkels sowohl für verformungsarme als auch für flexiblere Rastzapfen. more flexible locking pin application finds. A cone angle between <α <45 ° is thus suitable as a function of selected cone angle for both low-deformation and flexible locking pin.
Die Verformbarkeit des Rastzapfens ist zum Eingreifen des Rastzapfens in die Rastlochöffnung beim Zusammenfügen bzw. Aufeinanderstecken der Isoliergehäuse zur Bildung eines Klemmblocks von Bedeutung. Daher sieht eine bevorzugte Weiterbildung der Erfindung vor, dass der Rastzapfen am Rastzapfenende eine Ausnehmung aufweist. Vorzugsweise ist die Ausnehmung ein Einschnitt in einer Richtung senkrecht zur Achse des Rastzapfens. Auf diese Weise kann der The deformability of the locking pin is for engaging the locking pin in the locking hole opening when assembling or stacking of the insulating housing to form a terminal block of importance. Therefore, a preferred embodiment of the invention provides that the locking pin has a recess at the locking pin end. Preferably, the recess is an incision in a direction perpendicular to the axis of the locking pin. In this way, the

Gehäusevorderseite 12 des ersten Isoliergehäuses 24 angeordneten Rastzapfen 14 in das auf der Gehäuserückseite 18 des zweiten Isoliergehäuses 26 angeordnete Rastloch 20 ein. Zudem greifen die an der Gehäusevorderseite 12 des ersten Isoliergehäuses 24 angeordneten Rasthaken 16 in die an der Gehäuserückseite 18 angeordneten Rastfallen 22 des zweiten Isoliergehäuses 26 ein. Auf diese Weise werden das erste Isoliergehäuse 24 und das zweite Isoliergehäuse 26 miteinander verbunden. Der Figur 4 ist zu entnehmen, dass der Rastzapfen 14 und das Rastloch 20 kegelstumpfartig ausgebildet sind, wobei der Durchmesser des Rastzapfens 14, ausgehend von der Gehäusevorderseite 12 in Richtung des Rastzapfenendes 28 und der Durchmesser des Rastlochs 20, ausgehend von der Gehäuserückseite 18 in Richtung des Rastlochgrundes 32, zunehmend sind. Auf diese Weise wird beim Auseinanderziehen der aufeinander gesteckten Isoliergehäuse 10 durch die kegelstumpfartige Ausgestaltung des Rastzapfens 14 und des Rastlochs 20 eine Rückstellkraft in einer Richtung Housing front side 12 of the first insulating housing 24 arranged latching pin 14 in the arranged on the rear housing side 18 of the second insulating housing 26 locking hole 20 a. In addition, the locking hooks 16 arranged on the housing front side 12 of the first insulating housing 24 engage in the latching traps 22 of the second insulating housing 26 arranged on the housing rear side 18. In this way, the first insulating housing 24 and the second insulating housing 26 are connected together. The figure 4 it can be seen that the locking pin 14 and the locking hole 20 are formed frustoconical, wherein the diameter of the locking pin 14, starting from the housing front side 12 in the direction of the locking pin end 28 and the diameter of the detent hole 20, starting from the rear housing side 18 in the direction the Rastlochgrundes 32, are increasingly. In this way, when pulling the stacked insulating housing 10 by the truncated cone-like configuration of the locking pin 14 and the locking hole 20 is a restoring force in one direction
senkrecht zur Ebene der Gehäusevorderseite 12 bzw. der Gehäuserückseite 18 generiert, welche die generated perpendicular to the plane of the front of the housing 12 and the housing rear side 18, which the
aufeinandergesteckten Isoliergehäuse 10 aneinander zieht.successive insulated housing 10 pulls each other.
Auf diese Weise kann ein spielfreier Sitz der In this way, a play-free seat of
aufeinandergesteckten Isoliergehäuse 10 erzielt werden. Weiterhin ist ersichtlich, dass das Rastzapfenende 28 abgerundet ist. Auf diese Weise wird das Einführen des kegelstumpfartigen Rastzapfens 14 in die Rastlochöffnung 34 des Rastlochs 20 erleichtert. successive insulated housing 10 can be achieved. Furthermore, it can be seen that the locking pin end 28 is rounded. In this way, the insertion of the frustoconical detent pin 14 is facilitated in the detent hole 34 of the detent hole 20.
Der Rastzapfen 14 und das Rastloch 20 haben einen The locking pin 14 and the locking hole 20 have a
Kegelwinkel von ca. 10°. Ein derartiger Kegelwinkel eignet sich besonders für verformungsarme Rastzapfen 14. Cone angle of approx. 10 °. Such a cone angle is particularly suitable for low-deformation latching pin 14th
Zur Erleichterung des Einführvorgangs des Rastzapfens 14 in die Rastlochöffnung 34 weist der Rastzapfen 14 am To facilitate the insertion of the locking pin 14 in the locking hole 34, the locking pin 14 on
Rastzapfenende 28 eine in Achsrichtung des Rastzapfens 14 angeordnete konische Ausnehmung 36 auf. Auf diese Weise erhält der Rastzapfen 14 eine Wandung, wobei das Locking pin end 28 a arranged in the axial direction of the locking pin 14 conical recess 36. In this way, the locking pin 14 receives a wall, wherein the
Rastzapfenende 28 zum Einführen in die Rastlochöffnung 34 verformbar ist.  Locking pin end 28 for insertion into the locking hole opening 34 is deformable.
Zur Erhöhung der Stabilität des Rastzapfens 14 unter To increase the stability of the locking pin 14 under
Beibehaltung einer gewissen Steifigkeit des Rastzapfens 14 beträgt die Tiefe der Ausnehmung 36 ca. 80% der Länge des Rastzapfens 14. Auf diese Weise weist der Rastzapfen 14 einen Rastzapfengrund 38 auf, welcher der Anbindung des Rastzapfens 14 an die Gehäusevorderseite 12 eine hohe Retaining a certain rigidity of the locking pin 14, the depth of the recess 36 is about 80% of the length of the locking pin 14. In this way, the locking pin 14 has a locking pin base 38, which the connection of the locking pin 14 to the housing front side 12 a high
